自卸运输不仅对运输企业的经济效益有影响,且可减少卸货港的建设投资,降低卸货成本,提高泊位利用率,从而提高港口投资经济效益。本文只研究对航运本身的经济效益。 一、研究条件的设置 为了简化研究的问题,取航道为库区深水航道,航宽、弯曲半径对所取的船队没有限制,平均流速为零。 营运组织采取一顶二艘千吨级半分节驳顶推船队。驳船的主尺度与主要参数为:总长62米,水线长60米,型宽10.6米,吃水2.3米,方形系数0.91,非自卸的同样主尺
Dump transportation not only has an impact on the economic benefits of the shipping enterprises, but also reduces the construction investment in the port of discharge, reduces the unloading cost, and improves the utilization ratio of berths, thereby enhancing the economic benefits of port investment. This article only studies the economic benefits of shipping itself. I. SETTING OF RESEARCH CONDITIONS In order to simplify the research, there is no restriction on taking the fleet as taking the waterway as the deepwater channel in the reservoir area, the breadth of navigation and the bending radius, and the average flow velocity is zero. The operating organization adopted a two-tonne half-knot barge pushing the fleet. The main dimensions of the barge and the main parameters are: total length of 62 meters, water line length of 60 meters, width of 10.6 meters, draft 2.3 meters, the square coefficient of 0.91, the same non-self-dumping the main ruler
